Evaluation of academic institutional Websites: A Case Study of Saudi University Websites Sahar A. El_Rahman Abstract Website is a software product used by different organizations for marketing and information exchange. It is one of the best technologies for information system applications.  Generally, universities have complex websites, which include a collection of many sub-websites related to the different sections of universities. This work employed software tools-based evaluation method and evaluator-based evaluation method to comprehensively evaluate five big university websites in Saudi Arabia that are King Saud University (KSU), King Faisal University (KFU), Princess Nourah Bint Abdulrahman University (PNU), Prince Sultan University (PSU) and Dar Al Uloom University (DAU). The evaluation involves testing sample pages related to the selected universities. This study provides an overview regarding the weakness and strengths of the five Saudi university websites. W...

Scalable Unsupervised Ensemble Algorithm For Effective Insider Threat Detection Ajayi Adebowale, Ajayi Olutayo, Idowu Sunday, Ogbonna A.C, Otusile Oluwabukola Abstract Insider threats remain one of the oldest and notorious threats to information security. Early detection remains key to preventing insider attacks on an information system. The vast amount of enterprise data and the little data points pertaining to insider threats calls for techniques to handle the rare class problem. This study conceptualised insider threat data as a streaming data problem.  Scalability of insider threat detection systems represents a gap in knowledge in this disposition. Building on existing unsupervised ensemble stream mining techniques, this study proposed an insider threat detection algorithm and evaluated it using Centre for Analysis of Internet Data (CAIDA) Anonymized trace dataset for 2015. CAIDA datasets was used to ascertain the scalability of quantised dictionary construction...

MODELLING SCREW PROPELLER CHARACTERISTICS FOR OPTIMAL PERFORMANCE Adumene Sidum, Ombor Pereowei Garrick Abstract For the screw propeller to operate optimally there is the need to model the propeller characteristics using its hydrodynamic parameters. This work entails the use of MATLAB to model the performance characteristics of the propeller taking into consideration the propeller design equations with reference to the methodical series. The performance analysis was done with a four (4) bladed propeller with varying blade area ratio (expanded area ratio) of 0.4, 0.55, 0.70, 0.85 and 1.00. The performance (including cavitation criteria effects) of the largest possible optimal diameter was evaluated. The results show reasonable values of diameter for all the BAR’s except for expanded area ratio of 0.4 where a value of 8.75m larger than the draft was obtained and thus unacceptable. A table of propeller hydrodynamic values (diameter, open water efficiency, area and area ratios...

Secure authentication using the skin tone detection with the help of Advanced Encryption Standard and Steganography Ekta Chauhan Abstract Filtering  of image content, compressing the content aware image and video applications of color balancing can advantage from automatic skin detection in the images. Biometric characteristic used for usage skin tone images region steganography. Here significant information is implanted within the skin image region which will provide an outstanding data hiding secure location. For this detection of skin tone is required to be performed. Various information hiding steps can be used through image cropping. Image cropping better security than information hiding without cropping the complete image, so works of crop region as a key at decoding region. AES cryptography algorithm is used to convert secret data into an unreadable form previously embedding; which gives a strong backbone for information security. Steganography is the hiding ski...

Effective Team Formation in A Multi-Cultural Information Technology Project Environment; the challenges and Solutions AJAYI S. Wumi Abstract A major concern while handling multi-cultural projects in Information Technology (IT) organization is the large number of differences that exist amongst team members. These differences exist in various forms such as diversity in languages, orientations, educational background, sex, personal beliefs and cultural or ethnical differences.  Since most projects in IT organizations are scheduled to be undertaking within a time boundary and sometimes with constrained budgets by these same mixture of experts (irrespective of their differences) then, there is need to promote unison, empathy, professionalism, equity and sense of belonging amongst them to enable them (team members) overlook their individual and collective differences while functioning in their respective tasks to achieve management desired goals of time and quality. Otherwis...

Automatic Intelligent Real-time Intrusion Detection System: A Data Mining Model Oriola Oluwafemi Abstract Intrusion Detection System (IDS) is a popular device for securing network resources. However, developing a system that will automatically detect all known and unknown network attacks accurately in real-time is still a serious challenge. In this paper, a data mining model of an automatic intelligent real time network intrusion detection system that will be able to detect malicious network packets with very minimal false positive and false negative was presented. A three-layered Intrusion Detection System was modelled using Clustering techniques, Artificial Neural Networks and Decision Tree Classifiers. The algorithms used for each stage of the process were compared. Simple K-Means and Expectation Maximization Algorithms are compared in Layer One. In Layer Two, Multilayer Perceptron and Radial Basis Function Feed-Forward Back Propagation Neural Networks with varying para...

Synthesis of 2-oxoazetidine derivatives of 2-amino-5- methyl-thiazole and their antimicrobial activity Dr. Surendra Sonwane, Kanchan Kahar, Dr.Surendra Sonwane Abstract A new series of 3-chloro-4-(substituted phenyl)-1-{[2-(4-methyl-2-aminothiazolyl)-ethyl]-amino}-2-azetidinones, compounds  4a–j, has been synthesized from 2-amino-4-methyl-thiazole as the starting material. The structures of all the synthesized compounds were confirmed by chemical methodology and spectral analyses, such as FT-IR,  1 H-NMR, 13 C-NMR and mass spectroscopy. All the final synthesized compounds 4a–j  were screened for their antibacterial and antifungal activities against some selected bacteria and fungi and for their anti-tubercular activity against Mycobacterium tuberculosis, and  their minimum inhibitory concentration (MIC) values were determined. The anti-inflammatory activities of the title compounds were screened using albino rats (either sex) and gave acceptable results....

Mobile Number Portability (MNP) in Nigeria Ominike Akpovi A. Abstract The Nigerian Communications Commission (NCC) introduced Mobile Number Portability (MNP) to allow subscribers switch between Mobile Network Operators (MNO) while retaining their mobile numbers. This paper gives an overview of MNP, the types and benefits and briefly discusses the Nigerian telecommunications landscape. Drawing on a sample of 80 mobile subscribers in Nigeria, this research work investigates the effect of mobile number portability (MNP) focusing on subscribers’ perception and reasons for switching operators and opinion about the MNP process. Findings suggest that expectation of improved Quality of Service (QoS), improved customer service and more competitive tariffs were key reasons of porting among subscribers. Keywords Mobile Number Portability (MNP); Mobile Network Operator (MNO); Quality of Service (QoS); Nigerian Communications Commission (NCC); Full Text: PDF
